Hi all ,
Me new to Cassandra , i was asked to migrate data from Oracle to Cassandra.
Please help me giving your valuable guidance.
1) Can it be done using open source Cassandra.
2) Where should I start data model from?
3) I should use java, what kind of jar/libs/tools I need use ?
4) How I decide
Hello there,
Let me get straight to the point. Yesterday our three node Cassandra
production cluster had a problem and we could not find a solution yet.
Before taking more radical actions, I would like to consult you about the
issue.
We are using Cassandra version 3.11.0. Cluster is living on AWS
Good time of day everyone,
I've got three questions on Cassandra paging mechanics and cluster usage
regulation.
1) Am I correct to assume that the larger page size some user session has
set - the larger portion of cluster/coordinator node resources will be
hogged by the corresponding session?
2)

you suggesting forced read repair by reading consistency of ONE or by bumping
up read_repair_chance?
We have tried from command line with ONE but that times out.

Hi All,
I need some help with deploying a monitoring and alerting system for our
new Cassandra 3.0.4 cluster that we are setting up in AWS East region.
I have a good experience with Cassandra as we are running some 2.0.16
clusters in production on our on-prem servers. We use Nagios tool to

Hi,
I recently upgraded our 16-node cluster from 2.2.6 to 3.11 and see the
following. The cluster does function, for a while, but then some stages
begin to back up and the node does not recover and does not drain the
tasks, even under no load. This happens both to MutationStage and
GossipStage.

Hi All,
I have designed a column family
prodgroup text, prodid int, status int, , PRIMARY KEY ((prodgroup), prodid,

The data model is to cater
- Get list of products from the product group
- get list of products for a given range of ids
- Get details of a specific product

We're using cassandra 2.0.9 with datastax java cassandra driver 2.0.0 in a
cluster of eight nodes.
We're doing an insert and after a delete like:
delete from *column_family_name* where *id* = value
Immediatly select to check whether the DELETE was successful. Sometimes the
value still there!!
Hi there,
We are working on an API service that receives arbitrary json data, these

The environment:
I have a 6 node Cassandra cluster. On each node I have:
- 32 G RAM
- 24 G RAM for cassa
- ~150 - 200 MB/s disk speed
- tomcat 6 with axis2 webservice that uses the datastax java driver to make
asynch reads / writes
- replication factor for the keyspace is 3

Hey folks,
I am dealing with a legacy CFs where super_column has been used and python
client pycassa is being used. An example is given below. My question here
is, can I make use of include_timestamp to select data between two
returned timestamps e.g between 1393516744591751 and 1393516772131811.
Hey Folks,
So I am creating, column family using pycassaShell. See below:

'text': 'UTF8Type',
'favorite_count':'IntegerType',
'retweet_count': 'IntegerType',
'expanded_url': 'UTF8Type',

Hi, I have a small cluster of 1.2.6 and after some config changes I started

Not sure that's related, but the changes I performed were to disable hinted

picture changes.
But anyway, that seems like

My cluster of 11 nodes running Casandra 1.1-5 is pausing too long for ParNew
GC, which increases our response latency, Is it a good idea to have a a smaller
HEAP_NEWSIZE so that we can collect more often, but not pause that long?
